Cold Forged Steel: Unsurpassed density: The special IGB Austria rifling is produced by forcing the tool through the barrel under tons of pressure. The result is precise, mirror polished barrels with great strength and durability.

Quality: IGB Austria barrels are machined on specially designed machines optimized for pistol barrel production to ensure the best quality.

Warranty: 50.000 rounds or 5 years for use of factory loaded ammunition according to C.I.P or SAAMI standards are unmatched on the world market.

Plasma Hardening: There is no better way. Diamond hard smooth surfaces without the known weaknesses of tenifer process (loss of material flakes on inner surfaces).

Quality Assurance: Each and ever IGB Austria barrel is checked for dimensions, function, and accuracy before leaving the factory.

All IGB products are “drop-in”, easy to install by experienced users. No gunsmith or permanent changes required!

1-5 Business days if in stock in the warehouse in Las Vegas, otherwise up to 7 weeks if sent from Europe.

IGB Austria Barrel Manufacturing Process:

How does it work?

During every shot which is fired from a standard barrel, the bullet powder usually continues to burn after the bullet exits the muzzle. This is felt by the flip and seen by the muzzle fire.

This patented barrel system permits the utilization

of a longer barrel, ensuring total powder burning inside the barrel without sacrificing the operation of the gun. Thus eliminating common malfunctions which frequently occur. By implementing these longer barrels, higher velocities are achieved while muzzle jump and recoil are greatly minimized.

Longer barrels stand out for increased accuracy.

Fig.2 When the bullet passes the ports, inside – in the Impulse chamber – the gas pressure is build up and the gas is then pushing the impulse ring on to the slide.

Fig. 3 After the bullet has exited the barrel, and the next cartridge has been loaded, the slide pushes the impulse ring back into its starting position.

The IGB Patent

The IMPULSE SYSTEM uses powder gases, collected via ports in the barrel and transfers this energy via a hollow chamber (gas collector or impulse chamber) and a sliding element (impulse transfer ring) to the slide. This impulse equalizes the mass irregularities and allows reliable function even with heavier or longer barrels.

System Use

The Impulse System was developed to eQualityuip pistols, which dispose of a Browning type lockup (i.e. Glock, Colt, CZ ) with barrels up to 42 cm (16″) length. Moreover, these units offer for the first time the advantage of using compensators or longer match barrels in combination with target loads. Abb. Glock 17 with IGB 10″ barrel and matching shroud.

The Shroud

The optical impression is similar to a sound suppression device. The IGB shroud, due to its open construction, does not suppress the sound, nor can it be altered to do so. The IGB shroud protects the barrel or the shooters hand against burns.

Test Report – “Swiss Gun Magazine” – Juni 2003

…due to the lack of mass to be moved – relative to a blowback design – the long barrel combination of 9mm Luger shoots calmly.

.. shooting caliber .357Sig is a little more exciting. Somewhat more kick, but not uncomfortable at all – and nowhere near the felt recoil of the Glock standard barrels in models 31 and 32.

… It became a very fun shooting, and more ammunition as originally planned was expended due to the 30 round magazine.

Major advantage gives a precision match barrel, which differs from the original barrel by best fitting, special profiles and last, but not least, by high-end steel material of high viscosity. In contrast to stainless – high-end steel with special hardening preserves the viscosity and lifetime of a barrel. No broken ramps, no cracking of cartridge housings. Lasting best results.

Standard was yesterday… Barrel Technology by IGB Austria is the TODAY.

State-of-the-Art – Barrel Technology from Austria

IGB barrel profile – hexagonal: polygonal

IGB Austria with its in-house blank production combines both of two worlds. The conventional field-groove profile is used for best control of bullets or lead bullets. If you have a closer look at the profile you find the angle between groove-to-field to be similar to a polygon (60°) with slightly rounded edges. For this reason, IGB barrels are having a longer lifetime and are more cleaning friendly than others.

Cold Forged Steel

Unsurpassed density. Hard on the surface, “soft” inside. The parameters of a barrel to be hard/viscous and flexible are not exempting each other, but are combined in IGB Austria Barrel Production. IGB Austria forces the tool through the barrel with tons of pressure. The result is a precise, mirror polished barrel with great vibration characteristic and durability.

Plasma Hardening Procedure

Barrels, made by IGB Austria get treated the modern way of Hardening – the Plasmanitration. Diamond hard smooth surfaces without the known weaknesses of the tenifer process (loss of material flakes on the inner surface). Plasmanitration delivers characteristically a very dark grey surface, is corrosion resistant and comes close to diamond hardness.

Quality Assurance

IGB Austria works with special in-house adapted machinery to ensure best quality and precision. IGB Barrel – even if they are sold as drop-in will always go to the edge of best fitting. Tolerances are kept tight and optimized for shooters needs.

Hexagonal Rifling:

Compatible with Reloader Ammo!

Providing a better gas seal around the projectile as polygonal bores tend to have a slightly smaller bore area, which translates into more efficient use of the combustion gases trapped behind the bullet, slightly greater (consistency in) muzzle velocities and slightly increased accuracy.

Less bullet deformation, resulting in reduced drag on the bullet when traveling through the barrel which helps to increase muzzle velocity.
